The green opposition LMP party is submitting a request for data of public interest in order to discuss at parliament alleged cost increases related to the upgrade of the Paks nuclear power station due to delays in the project, a lawmaker of the party said on Monday. Peter Ungar told a press conference that Prime Minister Viktor Orban had "admitted that ... Paks II is the worst business of the century" and also admitted a delay in implementation. Calculations on the project's rate of return were based on the assumption that the old blocs and the new ones would operate simultaneously for some time and the extra energy generated during this period could be sold abroad, Ungar said. However, the delays will prevent this scenario, he added.
